Title: Process for the bleaching of waxes or wax-like materials by oxidation and the new compositions of matter thus obtained
IPC: C11B11/00
Filed: 1957-03-04
Abstract: A process for bleaching waxes, or mixtures thereof with fatty acids comprises adding at least one partial oxidation product of one or more hydrocarbons that are solid at room temperature, and then bleaching the homogeneous mixture at an elevated temperature, usually 90 DEG -130 DEG C., with chromosulphuric acid (i.e. a solution of chromium trioxide in sulphuric acid).  The partially oxidized hydrocarbon, which is suitably a partially oxidized paraffin wax or polyethylene, may constitute up to 80% of the mixture, but is usually 10-70%, most of the oxygen present being contained in hydroxyl groups ; the oxidized hydrocarbon preferably has both an acid value and a hydroxyl value of 10-80.  The chain length of this oxidized material is the longer the more carbon atoms are contained in the chain in the wax and acid.  The wax and oxidized hydrocarbon may both be crude products, and the preferred wax is crude Montan wax, although carnauba, ouricuri, and candellila wax, beeswax, cane wax, peat wax may also be treated, if required in the presence of fatty acids such as behenic or arachidic acid. The bleached product may be esterified with monohydric alcohols having at least 15 carbon atoms or with polyhydric alcohols and then suitably partially neutralized with an alkaline earth hydroxide or with zinc oxide or hydroxide, whereby the hardness of the product is increased.ALSO:A process for bleaching waxes, or mixtures thereof with fatty acids comprises adding at least one partial oxidation product of one or more hydrocarbons that are solid at room temperature, and then bleaching the homogeneous mixture at an elevated temperature, usually 90-130 DEG C., with chromosulphuric acid (i.e. a solution of chromium trioxide in sulphuric acid).

Title: Improvements in the cultivation of micro-organisms
IPC: C12N1/22
Filed: 1928-03-08
Abstract: 318,649. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 8, 1928. Glucose &c.-Sugar solutions to be used for the cultivation of yeast and other micro-organisms rich in protein and fat, are prepared by hydrolyzing peat. The peat is hydrolyzed so that the sugars are gradually, accumulated by acting with the solutions obtained by the action of acids on peat on a fresh batch of initial material once or several times. To obtain a clear solution more of the neutralizing agent than would be necessary for complete neutralization is employed whereby the humous substances are precipitated. Clear solutions are also obtained by effecting a precipitation of phosphoric acid during or after the neutralization of the crude solution. The crude sugar solutions are treated with oxidizing agents such as gases containing oxygen before or during the precipitation of the phosphates. Thus, the hydrolysis may be effected in the presence of phosphoric acid, potassium phosphate or natural crude phosphate, or one of these may be added after the hydrolysis or after neutralization which may be with chalk, lime or the oxides or carbonates of other metals such as barium, magnesium. zinc or the like. Examples are given of the preparation of sugar solutions from peat which are used for growing Torula utilis or Torula-yeast with aeration.

Abstract: 214,408. Brunton, J. L. March 16, 1923. Operating and controlling doors by toothed - gear mechanism and by checks. -Comprises mean for securing the braked gravity lowering of a bulkhead door in successive automatic steps. The door 1, moved in guides 2 by the rotation of a shaft 9 through worm gearing 28 or a hand crank 29, is fitted with means for releasing the band brake 12 either from the handle 27 adjacent to the door, or from mechanism 20 on the bridge. The controlling mechanism comprises a rigid arched tube 15 through which the cord 24 passes from the handle mechanism 27 to the brake lever. One end of the tube is connected by a cord 16 to the drum 18 on the bridge, while the other end is secured by a cord 22 which is wrapped round and secured to the shaft 9. Whenever the brake is released, the descending movement of the door pays out the cord 22 and lowers the corresponding end of the tube. This reduces the total length of the loop in the cord 24 and so slackens this cord to allow a spring to re-apply the brake. The brake can be released in two ways : (1) by a direct pull on the cord 24 through the handle mechanism 27, and (2) by increasing the length of the loop by hauling on the cord 16 to raise the corresponding end of the arched frame 15 through the medium of the mechanism on the bridge. Thus successive movements of the mechanism 20 or 27 are necessary to lower the door with a corresponding step-by-step movement. The application of the apparatus to horizontally-sliding doors controlled by weights or springs is mentioned.
